The following report was excerpted from an email from the Commonwealth of Kentucky, Department for Public Health, Radiation Health Branch:

On May 18, 2016, a fixed gauge was discovered to have a failed shutter device at the licensee's site at West Centertown, Kentucky. There was a failure of on/off mechanisms on one fixed gauge to function as designed. Failure discovered during routine testing of on/off mechanism by licensee. The licensee has contacted a service provider to schedule removal/repair.

The licensee notified the Kentucky Department for Public Health on May 24, 2016.

The fixed gauge is in a remote area of the plant and no overexposures of personnel have occurred.

"Event description: On May 23, 2016 a Virginia Radioactive Material Program (VRMP) inspector performed a routine unannounced inspection of Superior Paving Corporation. The inspector discovered that on April 20, 2012, two Troxler Model 4640-B Portable Gauges (serial numbers 1384 and 845) containing 8 mCi of Cs-137 each, were damaged by fire. The fire burnt the storage box which contained the two gauges. The transport containers and plastics on the gauges were melted. However, according to the Radiation Safety Officer statement, the integrities of the sources were intact. On May 10, 2012 the two gauges were transported by the licensee to North East Technical Services (NETS) for disposal.

"A transfer record was available for review. The licensee will provide the agency (VRMP) a detailed report for review. There was no public health exposure or environmental release from this event."

The following information was received from the State of Oklahoma by email:

"Approximately [1300 CDT] today, [Oklahoma was] notified by Advanced Inspection Technologies [AIT] (OK-27588-02) that a radiography truck belonging to them had been involved in a collision with a tractor/trailer truck at [1118 CDT] today at mile marker 178 on I-44 near Stroud, OK. The driver of the radiography truck was killed and the truck partially burned. At the time it was carrying a 30 Ci Ir-192 source and a 25 Ci Ir-192 source. The truck was taken to the Oklahoma Highway Patrol facility in Stroud where [Oklahoma personnel] arrived at about [1400 CDT]. The darkroom, where the cameras were stored (QSA Model 880s), was partially burned but had not been opened. Initial surveys of the exterior indicated the cameras, which were normally secured near the darkroom door, had been thrown forward and come to rest just behind the cab. Shortly after [Oklahoma personnel] arrived, the AIT RSO arrived and the darkroom door was forced open. The cameras were recovered and surveys indicated the shielding was intact. Wipe tests of each were also collected. One camera was damaged but the sources were secure inside each [camera]. The cameras have been returned to the AIT facility in Sand Springs, OK and will be returned to QSA for repair or disposal."

"Limerick Unit 2 was manually scrammed from 100 [percent] power at 0900 [EDT] on 6/1/2016 in accordance with plant procedure OT-112 'Unexpected/Unexplained change in core flow' when both 2A and 2B Recirculation Pump Adjustable Speed Drives (ASDs) tripped due to an electrical fault. The shutdown was normal and the plant is stable in Hot Shutdown with normal pressure control via the Main Steam Bypass valves to the Main Condenser and normal level control using Feedwater. The Manual RPS actuation is reportable under 10 CFR 50.72 (b)(2)."

All rods inserted fully on manual scram and the plant is in a normal shutdown electrical line up. Unit 1 was not affected by this event.

"Nine Mile Point Unit 1 (NMP1) experienced a momentary loss of Secondary Containment due to both Reactor Building (RB) airlock doors being opened at the same time.

"At 1046 [EDT] on 06/01/16, both RB airlock doors were opened simultaneously for less than 5 seconds. This resulted in Secondary Containment being declared Inoperable (TS 3.4.3). The airlock doors were closed and Secondary Containment was restored to Operable.

"The event is reportable in accordance with 10 CFR 50.72(b)(3)(v)(c), 'Any event or condition that at the time of discovery could have prevented the fulfillment of the safety function of structures or systems that are needed to control the release of radioactive material.'

"The condition has been entered into the station's corrective action program and the NRC Resident Inspector has been notified."
